We have 2 reports about corrupted btrfs super block, which has some garbage in its super block, but otherwise it's completely fine and its csum even matches. This means we develop memory corruption during btrfs mount time. It's not clear whether it's caused by btrfs or some other kernel module, but at least let's do write time verification to catch such corruption early. Changelog: v2: Rename btrfs_check_super_valid() to btrfs_validate_super() suggested by Nikolay and David. Qu Wenruo (4): btrfs: Rename btrfs_check_super_valid() to btrfs_validate_super() btrfs: Add incompat flags check for btrfs_check_super_valid() btrfs: Add csum type check for btrfs_check_super_valid() btrfs: Do super block verification before writing it to disk fs/btrfs/disk-io.c | 58 ++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 51 insertions(+), 7 deletions(-) -- 2.17.0 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
